Give every inhabitant of the earth the right to worship God according to the dictates of their [sic] own conscience. This is a principle which we believe in as Latter-day Saints, we ever have believed in it, and it is a principle which even the laws of our country, the constitution of our government holds out to all of its citizens.

We say to all men, “Enjoy your religion, worship God according to the dictates of your own conscience.” We ask the same right as the children of God. We claim this by the Constitution and laws of our country, and upon this principle we have embraced the fulness of the everlasting Gospel of Jesus Christ.
